This invention relates ayehicle attachmentin the nature ofia rim contractor, LITE carrier. and spare tire lock. 1

One important object. of theinvention is .to provide a. novelportable device of this character combining. in itself a carrier for spare tires, arim contracting; device and a locking device to hold the spare tire against improperremoval. I

Asecond importantobject of the invention is to provide a novel 1'3Y ce of this character which can be readily" attached to an automobile. i

. ith the above andotherfobjects in view as will be hereinafter apparent, the invention consists in. general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed. 1

.In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 IS a face view of a certain spider herewith.

Figure 2 is a side elevation of the spider. Figure 3 is a side elevation of the upper parts in the position assumed with the spare tire secured thereon against removal.

Figure 6 is a face view of the parts shown in Figure 5. t

In the presentembodimentof the inven-v tion there is provided a main portion consisting of a spider having a hub 10 and a series of radiating rigid arms 11 preferably T-shaped in cross section. The hub 10 is threaded to receive the screw 12 and on the outer end of this screw. is provided a pair of spaced or fixed collars 13 between which there is rotatably mounted on the screw, a sleeve 14 having a pair of cars 15 projecting radially therefrom. Between the ears of each pair is pivoted one end of. an arm lfi the other end of which fits between a pair of ribs 17 formed. on the inner side of a shoe 18 having at the end adjacent to the respective. arm 11 an outwardly extending leg 19 provided on its outer end with a toe20 forming a rim engaging hook. Each of these legs and hooks carries a bearing roller engage the rim R on which. the spare tire.

not showmis carried. The outer end of the shoe. is "provided with an outwardly turned hook 22 engagingtheouter portion of said- Pivoted "to the extremity offt'he screwf12 is an operating lever 27 provided with'jan an ularly dis osedend 28 and this end and'at east oneoi position of the lever 27 so that the bow of a padlock may be fixed there through. Spanning each arm of the spider and held in a notch 30 is a detachable link 31 which en gages the leg 19 and holds the shoe adjustably to the spider in a vertical position.

In operatin we may assume that the parts are positione to receive a rim or rim and tire. In this case these parts will bein the position shown in Figures 3 and. 4. When in this position the rim R is slipped on to the shoes 18 as shown in Figure i. The lever 27 is then operatedto unscrew the screw 12 and thus ,force the sleeve 14 outwardly. Since this causes the arms 16 to move toward a position parallel to the spider arms 1.1 it leaves the outer ends of theseshoes as, shown in Figure 5. Since each shoe is 21 to enable it to move readily .andsecurely anda downwardly m g 26 the l end adjacentfto the. sp der.

the arms 16am pro vided with openings 29 which register in one angled between its outer and inner portions To contract the rim the latter is placed on the shoes with these shoes in the position shown injFigure 3 and the pins are moved n the slots to engage the notches 26 shown in dotted lines in Figure 4. Then by unscrewin the screw the inner part of each shoe is rawn towardthe center and the book 20 catches and contracts the rim.

There has thus been provided a simple and eflicient device of the kind described and for the pur e Specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and'described, but it is desired to include all such as properly come within the scope of the claims. 1

Having thus described the invention, what is claimed as new, is:

1. In a device of the kind described, a spider having a hub and arms radiatin t erefrom, an adjusting screw threaded into the hub, tilting shoes engageable with a tire rim supported on the spider. arms, a collar journaled on thescrew andheld to move longitudinally therewith,and link arms connecting said collar and tilting shoes to tilt the shoes as the, screw is moved, said link arms each having a cross pin at its outer end and the shoes each having a rib provided with a diagonally dis osed slot having lat- .eralnotches at its en s, the pin being m0v able in the slot for selective seating in said notches.

2. In a device of the kind described, a spider having a hub and arms radiating t erefrom,van adjusting screw threaded into the hub, tilting shoes engageable with a tire rim sup orted on. the spider arms, a collar journalbd on the screw and held to move longitudinally therewith, link arms connecting said collar and tilting shoes to tilt'the shoes as the screw is moved, said link arms each leaving a cross pin at its outer end and the shoes each having a rib g provided with a diagonally disposed slot having lateral notches at its ends, the pin being movable in the slot for selective seating in said notches, andan operating lever having one end pivoted to the screw and its other end adapted to lie beside a link arm in one position of the lever, said last end and arm having registerable openings for reception of a shackle. 1

In testimony whereof I aflix my signature.
